19th century T.U.S. "Trade Union Shears" manufactured in Sheffield by a trade union co-operative.
These famous shears were advertised for sale to shearers at a discount through the shearers' union the AWU and its newspaper the Worker.

Still making quality tools today Robert Sorby gained a strong reputation in North America, Australia, New Zealand, South Africa, and many parts of Europe.
-- Many Thanks to John Pyke for this infomation. Sorby & Wilkinson's Sheep Shears were first advertised in Australian newspapers in 1841.
